Ammonia distributor Yara Clean Ammonia (Yara) and global ocean transportation provider Höegh Autoliners, have agreed on a future supply deal for clean ammonia, according to Yara on Thursday (2 November).

In May 2023, the two companies signed a Letter of Intent to partner around the supply, potential distribution, and delivery for consumption of clean ammonia for the Höegh Autoliners’ new Aurora-Class PCTC vessels. The twelve Aurora Class vessels will be the world’s largest and most environmentally friendly car carriers ever built, equipped to operate on zero-carbon ammonia and methanol.

The partnership follows separate initiatives in both companies in two important parts of the value chain, namely supply and demand.

“This is exactly the type of collaboration that will accelerate a push towards net zero shipping in the deep-sea segment of the industry. For Höegh Autoliners, this represents another step towards full decarbonization of our customers’ supply chains, and we are pleased to collaborate with a strong Norwegian global player to meet this goal,” said Andreas Enger, CEO of Höegh Autoliners.

Both companies consider clean ammonia, produced either with renewable energy or from natural gas with CCS, as a future maritime fuel with high potential that will contribute to solving the greenhouse gas emission challenges associated with global maritime transportation. As part of the Letter of Intent, the companies will also consider the supply of blue ammonia where up till 95% of the CO2-emissions are captured and permanently stored.

Norway has set ambitious targets for cutting emissions from domestic shipping by 50 % by 2030. In July this year, the International Maritime Organization (IMO) adopted a historic ambition of zero emissions for international shipping by 2050. Clean ammonia is a solution that can contribute to reducing the world’s dependency on fossil fuels.

“Being the world’s largest ammonia distributor, Yara Clean Ammonia will be a significant contributor on the path towards zero emissions in the maritime sector,” said Magnus Krogh Ankarstrand, President of Yara Clean Ammonia.

“We aim at significantly strengthening our leading global position, unlock the green and blue value chains, and driving the development of clean ammonia globally. Building on Yara’s leading experience within global ammonia production, logistics and trade, Yara Clean Ammonia works towards capturing growth opportunities in net-zero fuel for shipping.”

Höegh Autoliners latest LNG dual-fuel PCTC en route to Shanghai for bunkering

Höegh Autoliners on Tuesday (20 May) said its latest liquefied natural gas (LNG) dual-fuel pure car and truck carrier has departed China Merchants Heavy Industry’s yard, ready to commence its commercial operations.

The 9,100 CEU Höegh Sunrise, currently sailing the seas, is on its way to Shanghai for bunkering before sailing to Japan and then towards Europe.

The PCTC is the fifth in a series of 12 Aurora Class vessels built by the shipyard in China. The first eight Auroras are or will be equipped with engines primed to run on LNG and low-sulphur oil.

These vessels can be converted to run on ammonia later. By 2027, Höegh Autoliners said the four last vessels of the series will be able to run net zero on ammonia directly from the yard when delivered.

Manifold Times previously reported the naming ceremony of Höegh Autoliner’s fourth Aurora Class newbuild, Höegh Sunlight, at Taicang Haitong Auto Terminal.

Singapore-based Seatrium receives AiP from ABS for ammonia bunker vessel

Singapore-headquartered marine engineering firm Seatrium on Tuesday (21 May) said it has secured an Approval in Principle (AiP) from classification society American Bureau of Shipping (ABS) for a 25,000m³ ammonia bunker vessel.

The company said the vessel has a 25,000m³ liquefied ammonia capacity, constructed using IMO Type C containment, designed by Seatrium Marine & Deepwater Technology.

The vessel is capable of dedicated ammonia bunkering with optional carrier functionality.

It is designed to operate with a deadweight tonnage of 19,500 mt at 14 knots, allowing for 55 days of operation without the need for refuelling.

The vessel’s features include enhanced safety architecture focused on preventing open-deck leaks, compliant with IMO standards, the IGC Code, and ABS regulations as well as integrated systems allowing a seamless switch between ammonia and diesel fuel.

“The ABS AiP verifies the technical viability and regulatory compliance of our vessel, creating a foundation for detailed engineering and construction,” the company said.

“This approval marks a crucial step towards timely delivery and positions Seatrium as a leader in maritime energy transition. Together, we are building a robust fuel infrastructure for the ZeroCarbon fleet of the future!”

ABS answers critical safety questions related to using ammonia as a marine fuel

ABS engineers examined realistic bunkering situations such as STS, terminal-to-ship and truck-to-ship, as well as ammonia dispersion from the vessel due to a leakage incident in the engine room.

Classification society American Bureau of Shipping (ABS) on Thursday (15 May) published its report to bring together the findings of its advanced research into the performance of ammonia on board.

Critical safety questions such as “how does ammonia behave when it leaks in an engine room?” and “how does a cloud of escaped ammonia disperse during bunkering operations?” are addressed in the latest ABS research.

ABS performed computational fluid dynamics (CFD) simulations using advanced tools to quantitatively assess the risks associated with ammonia dispersion in accidental leakage scenarios.

ABS engineers examined realistic bunkering situations such as ship-to-ship, terminal-to-ship and truck-to-ship, as well as ammonia dispersion from the vessel due to a leakage incident in the engine room.

“This publication provides a comprehensive report of ABS’ efforts to address the challenges and opportunities presented by ammonia as a marine fuel,” said Vassilios Kroustallis, ABS Senior Vice President, Global Business Development.

“Through detailed analysis of ammonia dispersion studies and emergency evacuation protocols, ABS is contributing to the discourse on safe and supportable maritime fuel alternatives, fostering a culture of preparedness and resilience.”

In addition to CFD simulation analysis, ABS leveraged the latest industry best practices and advancements in software and hardware – including acoustic cameras for detecting and visualizing ammonia leakage – to provide a thorough, three-part framework for owners and operators evaluating ammonia as a cleaner fuel source:

Proactive regulatory engagement and risk anticipation
Development and implementation of a multifaceted safety framework, combining qualitative and quantitative risk assessments
Real-time monitoring and optimized emergency response
